Too bad, Ken chan didn't talk much in their last appearance. You should listen to their radio to hear him more.
Aaah, you like kansai guy? that explains a lot. XD

well, Omi is the fashion leader in sandaime, they say. He also likes cooking. Very mature?...hmmm...you need to see more pictures of him to decide that. lol.

I think the one who's the maturity is Ken chan, he often acts like brothers for Omi, Ryu, ELLY & Gun chan when the two leaders were not around. He's such a great big brother.
(But I still prefer Ryu chan after all. ahahahha, sorry to imitate you. I saw him first!!! LMAO)
